Hopefully there will be a reason for the cluster, which will correspond to a particular category, but that can only be interpreted by the user. While deep learning strategies achieve outstanding results in computer vision tasks, one issue remains: The current strategies rely heavily on a huge amount of labeled data. The task of unsupervised image classification remains an important, and open challenge in computer vision. The ee.Clusterer package handles unsupervised classification (or clustering) in Earth Engine. SELF-SUPERVISED LEARNING First, extensive experiments are conducted and show that, for a given dataset, the choice of the CNN architecture for feature extraction has a huge impact on the final clustering. Get the latest machine learning methods with code. Various unsupervised classification algorithms exist, and the choice of algorithm can affect the results. Supervised classification uses observed data to teach an algorithm which combinations of red, green, and blue light (pixel values in an image) represent grass, trees, dirt, pavement, etc. Unsupervised Image Classification (Clustering) Unsupervised classification attempts to find clusters in n-dimensional space based on the reflectance values, and assigns to those clusters to a group. I discovered that the overall objective of image classification procedures is “to automatically categorise all pixels in an image into land cover classes or themes” (Lillesand et al, 2008, p. 545). Self-supervised methods generally involve a pretext task that is solved to learn a good representation and a loss function to learn with. UNSUPERVISED IMAGE CLASSIFICATION. Self-supervised representation learning has witnessed significant leaps fueled by recent progress in Contrastive learning, which seeks to learn transformations that embed positive input pairs nearby, while pushing negative pairs far apart.
